Why can’t I receive messages from Samsung a7 mobile card?

1. Restart your phone to see if it is a signal problem.

2. Try changing other SIM cards

3. Check whether the security guard or third-party SMS software is installed on the phone, uninstall it and test

4. Back up mobile phone data (phone book, text messages, multimedia files, etc.) and restore factory settings

If the above methods still do not work, please send the device to a Samsung service center, and engineers will check the machine and handle it.
